ELECTROMAGNETIC SHIELDING EFFECTIVENESS OF ALUMINIUM EPOXY COMPOSITE PLATES IN S AND X BAND
Keywords:
Electromagnetic Shielding, Aluminum Particulate Composites, Taguchi methodsAbstract
In today's modern world, humans are more exposed to Electromagnetic (EM) waves from various sources. So an effective shielding from the harmful effects of EM waves is required. A shielding material is one which is conducts the EM waves and thereby not allowing it to interfere with humans and instruments which require high precision. As EM radiations are hazardous to environment, studies have been carried out to develop an effective electromagnetic shielding material. The present work concentrates on developing an EM shielding materials through aluminium epoxy particulate composites. The specimens are tested in the X band (8 GHz to 10 GHz) and S band (2 to 4 GHz) in EM spectrum. The results are compared for EM shielding effectiveness of aluminium particulates composites of various micro structures using Taguchi methods. The experimental results show that shielding effectiveness of plain polymer is improved by reinforcing it with aluminium particles.
